'0 all whom it may; concern Be it known that l, CLEMENT F. STREET, a citizen of the United States, residing at the borough of Manhattan, in the city, county, and State of New York, have invented a certain new and useful Improvement in ControllenCam Devices, of which improvement the following is a spec1fication.

This invention relates to means for supplying fluid pressure intermittently or periodically for any suitable purpose where it is desired to utilize the fluid under pressure in. series oi'blasts of greater or less frequency and duration, and has for its ObJECt toprovide an improved cam device for controlling the successive admissions of fluid r for other purposes.

While my improvement is adapted for a variety of uses, to he employed in connection with a mechanical stoker for forcing the fuel into the nehon, as shown and described in my prior pending epplioation Ser. No. 565,579, filed June 7. 1910. In this prior construction, the admission of fluid under pressure to the fuel distrihuter nozzles is controlled by a valve operated. by a pivoted lever one-end of which carries a roller bearing upon the periphery of a. cam disk upon which the cam members are pivoted and adapted to be turned to different positions to extend the different cam surfaces, beyond the periphery of the dish .to engage the roller and actuate the valve.

According to my present the cam members are the cam body or disk, handles and spring improvement, rotatably mounted on and are provided with actuated locking mechtively lock each cam member against accidentalmovement from any position to which it may be adjusted, but adapted to be released by a certain movement of the handle and the: turned to any other of its positions, as desired.

tion; Fig. 3, a central transverse section of the cam device; Fig. 4, a face view of the body portion of the cam disk, with the cover and cam members removed; Fig. 5, a verlicai transverse section of the same, taken on the line 5-5 of Fig. 4:; Fig. 6, a front elevation of the cover plate, portion being broken away; Fig. 7, a vertical transverse section of the same, taken on the line 7-Z or" 6 Fig. 8, a perspective view of one of the cam memebers; and, Fig. 9, a perspective view of one of the handle members.

As set forth in my mior application, the valve for controlling the'supply or flow of the fluid under pressure comprises a casing, 32. containing a valve proper, 31, with stem, c4, and a spring, 33,, normally holding the valve closed on its' seat, the casing having a bracket arm, 37, to which is pivoted the lever 36, adapted to operate the valve'stem and at the other end carrying a roller which bears against-the cam disk.

According to the preferred construction shown in the drawings, the cam disk comprises a. body portion, 35, and a cover plate, 35, mounted on a shaft, 45, and having one or more cam, members, pivotally mounted on said body portion and adapted to be rotated by means of handles, 42, so that the cam surfaces, 40, at the ends of said cam members, 39, may be either extended beyond or drawn within the periphery of the adjustment.

In order to normally and positively lock the cam members in any position, and thus prevent any accidental turning movement of the same, I provide a spring actuated I released by a preliminary movement of the can. handle before turning the same and thecam member to another position. According to the construction shown, the cam members are each provided with a square, or'other non-circular opening, 48, each arranged in line with a corresponding opening, 52, in the cover plate, 35*, and'the stem of each. handie, 42, isprovided with a square or corre sponding non-circular end portion, 51, slid ably mounted in said openings in the cover plate, and cam member, and having :1 limtransverse movement therein inn dirc tion substantially perpendicular to the.

of the cam.

a pin, M

The stem is also guided supporled in tion, and carrying a. spring, 49, whicfi acts '1' between the body and said handle to normally hold the square end portion, 51, of

the stem in engagement with the opening. in the cover plate, and thereby positively lock the handle and cam member against rotation.

stem, 43, is made smaller or of circular cross. section, and may be rotated withln the non The intermediate portion of the circular opening, 52, of the cover p1ate,.so' that when the handle and stem are moved transversely in the openings by being pushed inward against the spring, 49, thesquarsr end portion, 5 1, of the stem passes wholly within the opening, 48, in the cam member, and the handle and cam member nay then be turned to any other position tolfadjust or withdraw the, cam as desired. Inthisway,

any accidental rotation of the cammembers is positively prevented'as it is necessary to release the spring actuated locking mechanism by the preliminary or transverse moveeither extend or withdraw one of the cam surfaces.

It will now be seenvthat I have provided a simple and eiiicient cam device in which the cam members are normally positively locked against rotation, but may be readily released by a preliminary movement of the handles and then adjusted to any desired position.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is:
